    Momentary switch

    If the images were larger it might be possible to read what's written on the casings. I've searched the site, and it doesn't say anywhere what they use in their switches.

    Momentary switch

    Yes, you're right Hotwaterwizard. They look very expencive, and I wonder if that company would be will to ship three of those to me in Sweden if I ordered them.

    Momentary switch

    There are a lot of toggle switches - spdt and the like. They move between two or more positions in a straight line (up and down). I also know there is a kind that can move up and down and sideways with 4 or 8 positions, but I don't know what they're called. When I search for joystick switches I...

    Fiber Optics

    Fibre optics always transmits light, it's just a question of what kind of light you pass through the fibre and what happens to it at the other end. My experience so far has to do with lights in models, and on a more theoretic basis; fibre optic high speed data transfer (broadband). The...

    help "EtCHING technique"

    One way is to print out the PCB-design using a lazer-printer and iron it on. Several pages popped up when I googled.

    Fiber Optics

    My first fibre optics project was a StarTrek model called the Enterprise Insident with one Enterprise and two Romulan ships. It was TINY and needed a lot of shaping and fixing, but the result was great! My next project is a model of Deep Space 9 (DS9) with over a thousand tiny fibre optics...

    IC 555 instead of IC 50240

    OK. Thanks! It was a bit confusing. I'll try and "untangle" the schematic and see if I can find the places to "cut" away the digital parts.

    IC 555 instead of IC 50240

    ExpressPSB wasn't what I expected. I wanted it to put together a netlist based on the circuit diagram, but it didn't. I first drew the diagram in the part called ExpressSCH, but when I tried to import it into the PCB-part,all it could do was to show me where the parts were linked. I had to...

    Audioguru - the idea to have it follow the harp is nice. I haven't thought of that possibility. It should add some interesting effects  :) And yes, I do sing. My voice is my main instrument. MP - I'm beginning to understand the different parts in this. The PLL is a small part of a larger...

    Audioguru - imagine you're playing the piano and singing at the same time. Your voice is "playing" the melody. Your left hand is playing the base on the piano, and your right hand is filling in the chords. Your left hand can play one note, or maybe the octave as well, and your right hand playes...

    The "keyboard" is made from rotary switches. On the harp there is 4 knobs on the front, and a 5th knob on the top side. If I use one knob (the 5th) for volume control, I have 4 knobs for my keyboard. My latest idea on how to use those knobs is based on a couple of circuits I found on a...

    MP and Ldaniel - Thank you both! Background and wanted result: I have musical training in song, piano, guitar, etc. in part as a music teacher (didn't graduate because of the little *@#!!?s), and a strong base of music theory. I've alsways been good at putting things together and my feminin...

    MP - is this what you mean? http://www.synthdiy.com/show/showproduct.asp?show=942 I've also been looking closer at the http://www.uni-bonn.de/~uzs159/-site. Both look promising. I am however a bit at a loss as to put the parts together for what I have in mind. I guess all the knobs in the...

    Rotary switches ore pretty common in model railway setups, so I will use those for the preset chords. The scales... Consider the C major scale (all white keys on a piano). It has a minor parallel (using the same keys) called A minor. I will have one rotary switch for the C major scale and...
